An anti-tumor film of biodegradable polymers is in the form of a two-layer film, in which the first layer adjacent to the tissue is composed of a destructible polymer and an anti-tumor preparation, and the second layer is composed of the same or of another destructible polymer, the biodestruction time of which exceeds the time of release of the anti-tumor preparation in the first layer, the second layer representing between 0.1 and 0.8 of that of the first layer . |
